GIG FOR NAPPINGCLOTH.

EPBCIFICATIOEQ' forming part of Letters Patent No. 322,983, dated July 28, 1885.

Application filed April 17, 1884. (No model.) Patented in Canada May 1-1, 1884, No. 19,333.

The invention relates to gigs for napping.

cloth; and it consists in the peculiar combinations and the construction and arrangement of parts hereinafter more particularly described, and then pointed out in the claims.

The drawing shows a perspective view of part of a gigging or napping machine with my invention applied thereto, a portion of the frame being broken away.

As my invention relates to the particular driving mechanism and the means for regulating the tension of the belt, it is not necessary to illustrate or describe the entire ma chine.

The cylindrical brush B, which is made of any suitable material, is provided wit-h a spindle, B, suitablyjournaled.

With the view of permitting the brush B to be adjusted, I fit the j ournal-boxes G for the spindle B in vertical slots formed either in the main frame, or, as indicated in the drawing, in the hangers D attached to it, as shown.

E are set-screws located at the bottom of the hangers D, and utilized for the purpose of imparting a vertical adjustment to the boxes O, with the view of moving the cylindrical brush nearer to or farther from the surface of the teasles A.

F is a pulley located on and fastened to the spindle of the napping-cylinder A,and driven by any suitable power applied to the pulley F secured to said spindle.

G and H are two small pulleys journaled in the T-arm I, which is pivoted on the main frame of the machine, as indicated.

J is a small pulley on the spindle B of the cylindrical brush B.

K is an endless belt passing around the pulleys F, G, H, and J, as shown. As these three latter pulleys are much smaller than the pulley F,the speed of the cylindrical brush B ried around the pulleys G, H, and J, so as to make the cylindrical brush revolve in the opposite direction to that in which the nappingcylinder revolves, the surface of the cylindrical brush B and teasles A, which are fixed to the surface of the napping-cylinder A, will move in the same direction. Consequently, While the greater speed of the cylindrical brush, acting on the teasles, will thoroughly cleanse them of any flock which they may have gathered from the cloth, the revolving brush will in no way injure the teasles, which it might were it caused to revolve so that the surface of the brush and teasles in contact with each other traveled in opposite directions.

The object of pivoting the arm I ,which carries the small pulleys G and H, is to provide an easy method of tightening the belt K, as it will be seen that it is merely necessary to move the arm Ion its pivot in order to tighten or loosen the belt, and as means for holding it at any desired point can readily be provided, the belt can always be held tight, and it also allows the adjustment of the cylindrical brush B without interfering with the length of the belt In order to, show a means whereby the T- arm I may be adjusted, I provide the same with a set screw, 1, passing through the arm and bearing on a projection, i, on the main frame. Thus when the screw is turned in one direction, the arm will be forced away from the projection '1', thereby tightening the belt, whereas if turned in a reverse direction the arm will approach the projection, thereby permitting a slacking of the belt K.

By my arrangement of pulleys I am enabled to drive the napping and brush cylinders in a reverse direction, the latter at a higher rate of speed,with a single belt connecting the two, as the power is applied directly to one of the cylinders, thereby dispensing with the pulleyshaft and eXtra belt commonly employed between the two cylinders in this class of machinery Where the brush and napping cylinders revolve reversely, the former at a higher rate of speed than the latter.

On referring to the drawing it will be seen that the belt K, after passing over the pulley F, and the pulleys G and H, attached to the IOC arm I, hasa return fold between the latter pulleys the bight of which embraces the pulley J thereby causing a greater frictional contact between said belt and pulley J than would occur if the belt passed direct from the pulley F onto the pulley J, as in such case, owing to the great difference in diameters of the two pulleys and their short distance apart, there would be but little contact between the belt and pulley J.

\Vhat I claim as new 1s 1. The nappingeylinder A, provided with teasles A, and the cylindrical brush B, bearings therefor working in the slotted hangers D of the main fra1ne,and the set-screws E, for adjusting said bearings, in combination with the pulleys F J, secured, respectively, to the shafts of the cylinders A B, the pulleys G H, the belt- K, and means for adjusting the pulleys G H, whereby the same tension of belt may be preserved on the adjustment of the cylinder B, substantially as described.

2. The napping-cylinder A and the brushcylinder B oppositely revolved, and the pulleys F J, secured, respectively, to their shafts, in combination with the pulleys G H, located at a distance from the pulley F in line with an d beyond the range of pulley J, and the belt K, passing over the pulleys F and G H, and returning on itself between the two latter pulleys, the bight of which embraces the pulley J, as and for the purpose set forth.

3. The belt K and pulleys F, G, H, and J, in combination with the T-arm I, carrying the pulleys G and H,and the main frame, substantial] y as and for the purpose specified.
